Abstract: 1,257,215. Electrohydrodimerization process. MONSANTO CO. 5 Feb., 1969 [9 Feb., 1968], No. 6223/69. Heading C2C. [Also in Division C7] Hydrodimers of olefinic compounds are produced by passing electric current through an aqueous olefinic nitrile-, ester- and/or carboxamide-containing catholyte separated from an aqueous acidic, e.g. H 2 SO 4  anolyte by a solid cation-permeable membrane of a conductive polymeric matrix reinforced by at least two parallel sheets of woven glass fabric embedded therein. Preferably, the matrix comprises a copolymer of a polyvinyl aromatic (e.g. divinyl benzene, naphthalene, diphenyl or alkyl-substituted derivative thereof) compound and a monovinyl aromatic (e.g. vinyl naphthalene or alkyl-substituted derivative thereof) compound having sulphonic groups bonded to the aromatic nuclei of the copolymer. The catholyte may contain a quaternary ammonium or amine alkylsulphate or sulphonate. The electrodes may be of Pb or alloy thereof. For example, acrylonitrile may be continuously hydrodimerized to adiponitrile in a series of cells using tetraethylammonium ethylsulphate as the electrolytic salt in the catholyte and sulphonated divinylbenzene-styrene copolymer as polymeric matrix for the cation-permeable membrane.

Title: Electro-photographic aluminium (alloy) base pretreatment - with semi-conductor improves bonding with selenium, cpd. or alloy
Inventor: BERLE JOHANNES
IPC: G03G5/10
Filed: 1973-07-30
Abstract: In the prodn. of an electrophotographic recording material from Se, Se cpds or Se alloys on a conducting base of Al (alloy), esp. an Al-Mn alloy, the surface of the base is pretreated with the photoconductor to produce an intimate bond and then the photoconductor is applied. The photoconductor is applied. The photoconductor pref. is deposited from the vapour phase. The bond can be produced by heating the base above 200 degrees C, pref. to 230-280 degrees C and then exposing to a Se vapour atmos.; by heating the Se-coated base above 220 degrees C, pref. to 220-300 degrees C in a closed appts., so that the Se film evaporates and forms a bond; or by immersing the heated base in a colloidal Se soln. Excellent adhesive strength is obtd., making the photoconductor film insensitive to shock and pressure. This facilitates use and gives greatly improved life, esp. when a flexible base is used. No additives are employed which could be detrimental to the electrophotographic properties. The high adhesive strength allows the use of a base with a very smooth surface, which gives high quality copies.

Title: Single or multi-stage motor driven vacuum pump - has flexible plate acting as noise damper over outlet aperture
Inventor: LEBLANC JUN JOSEPH ALEXANDER
IPC: F04C23/00
Filed: 1973-08-09
Abstract: Vacuum pump has a block which forms a pump chamber, in which a rotor is fitted with an outwardly prestressed vane moving radially. An inlet opening is provided, and at a distance from it an outlet opening, which are so arranged that when the rotor vane moves from the inlet opening to the outlet opening, it moves firstly inwards and then outwards. An oil container partially encompasses the chamber. A flexible plate fitted outside the chamber and inside the container at the outlet opening acts as a noise damper forms a narrow gap, which is limited by a sunker recess of the block partly surrounding the outlet opening. The plate is fixed at a point away from the outlet opening and its free end extends over that opening. The pump can be of the two stage type with a rotor component in each stage but running on a common shaft. In the two chambers inlet and outlet apertures are provided and the outlet of the first chamber is connected to the inlet of the second. A drive motor is connected by direct coupling to the pump shaft.

Title: Wear indicator for railway disc brakes - spring loaded piston vents pneumatic pressure following excessive wear
Inventor: WOSEGIEN BERND DIPL ING
IPC: F16D66/02
Filed: 1974-03-06
Abstract: Compressed air is fed, via a restrictor and a control switch in parallel, to a sensing unit on each of the disc brakes and to an indicator unit. The sensing unit consists of a block (2) in which slides a spring loaded piston (12). A pivoted arm (10) attached to each disc pad bears on the piston. With little or no pad wear the piston blocks the compressed air flow to atmosphere (7 to 0), but as brake wear increases the piston is pushed further against the spring till air escapes to the atmosphere. This registers as a drop in pressure on the indicator. The arms (10) bear on the piston at two points spaced along the disc pad periphery.

Title: Current collector for homopolar motor - with liquid metal contact medium has pressure regulating means using restrictors
Inventor: MASSAR ERNST DR
IPC: H02K31/04
Filed: 1974-04-05
Abstract: The application is primarily to very heavy current low speed homopolar motors, for example as used in ship propulsion. The liquid metal is forced into the gap between rotating and stationary members of the contact assembly by means of a pump. The fluid enters at the top of the assembly and flows in parallel paths round both sides of the rotor, leaving at the bottom to return, via a cleaner and cooler, to the pump. To counteract the increase in pressure of the liquid between top and bottom due to column height, pressure reducing restrictions may be placed in the gap.
